Abstract:
A method for assessing the release performance of microcapsules comprising at least one volatile ingredient, the method comprising the steps of: • a. applying a plurality of said microcapsules to an underlying surface; • b. applying a kinetic frictional shear stress c through a contact surface of a probe under a predefined load, a predefined contact surface area and a predefined shear rate to said plurality of microcapsules; and • c. measuring the amount of the at least one volatile ingredient released per second from said microcapsules under said kinetic frictional shear stress τ.
Abstract:
A mobile-platform imaging device uses compression of the target region to generate an image of an object. A tactile sensor has an optical waveguide with a flexible, transparent first layer. Light is directed into the waveguide. Light is scattered out of the first layer when the first layer is deformed. The first layer is deformed by the tactile sensor being pressed against the object, A force sensor detects a force pressing the tactile sensor against the object and outputs corresponding force information. A first communication unit receives the force information from the force sensor. A receptacle holds a mobile device with a second communication unit and an imager that can generate image information using light scattered out of the first layer. The first communication unit communicates with the second communication unit and the mobile device communicates with an external network.
